My dog needs to be muzzled for vet visits. I just can’t get one on, she goes crazy. I’ve tried the gentry slowly method, and it was going ok, but the problem comes as I can’t clip the damn thing quickly enough, then she knows it’s being attempted, and it’s a lost cause. Can anyone recommend anything that is very easy to fit and also how best to deal with being aggressive to me when I try to put it on. It’s a nightmare. I’ve tried Baskerville and the sleeve types. Crossbreed collie.
